Such theme is well-known.
In order to calculate the operation of rolling in advance on technology, what be necessary is by corresponding precise analytic model the operation of rolling to be simulated.Such model itself is known.Therefore for the purpose of design of heavy plate mill row and other plate mill row and bar steel milling train row such as the model that uses high precision.These models are most to come work with shape function (Ansatzfunktionen), and described shape function is based upon on the basis of finite element analysis method.By means of such model, especially can carry out modeling to the material flow of the rolled piece in the roll gap well.This is not only applicable to pure flat pass and is applicable to upset pass and the order of flat pass for the rolled piece of band shape, wherein reduce the thickness of banded rolled piece in flat pass, and wherein hinders spreading of banded rolled piece in upset pass.Especially for the order of upset pass and flat pass, not only the so-called dog bone that occurs in upset pass is formed phenomenon (Hundeknochenbildung) but also the so-called bulge that occurs in flat pass is formed phenomenon and necking down and form phenomenon and carry out modeling and carry out quantitative calculating in advance.For the result of flat pass, also can calculate the profile and the glacing flatness of banded rolled piece with excellent precision in advance.
Finite Element Method is with very high resolution ratio work.For feasible computer power today, need a plurality of hours time to calculate in advance.These models be not suitable for continuing several seconds in line computation.Thereby in scope in line computation the use experience model.But described empirical model is not suitable for such as the accurate conclusion that provides when processing banded rolled piece about ribbon shape, strip profile and strip flatness.
Summary of the invention
Task of the present invention is, some schemes are provided, can be quantitatively the material flow that occurs is carried out modeling than the simple mode of prior art in the operation of rolling by means of these schemes.
This task is resolved by the generation method with the described feature of claim 1 aspect method and technology.The favourable design of described generation method is the theme of dependent claims 2 to 9.
By the present invention, be the basic frame setting within the scope of setting of being in that is in base state within the desired state range and some based on the some of the basic model rolled piece given in advance of the general shape function of the equational use of mathematics-physics.By means of described basic model, correspondingly try to achieve output state.Every kind of output state is described by the weight factor of some, described weight factor correspondingly shows, the corresponding respectively shape function of described general shape function to what extent occurs in rolled piece after the corresponding base state by rolled piece and corresponding basic frame are provided with the defined operation of rolling.By overall analysis, try to achieve the shape function that matches to the output state of being tried to achieve.The number of the shape function that matches is significantly less than the number of general shape function.Generate described rolling model under the situation of using the described shape function that matches, wherein this rolling model is based on the equation of described mathematics-physics.Generate described machine code by means of described rolling model.
The present invention is based on such understanding, promptly for need computing cost based on the model of general shape function (such as already mentioned finite element), described computing cost and problem are not complementary.By the use of " correct " shape function (that is to say the shape function that matches), can effectively reduce this computing cost.The method step of claim 1 provides these shape functions.Then generate described model in known mode own according to the shape function that matches of being tried to achieve.
Can " intelligently " to the output state of being tried to achieve totally analyze and " intelligently " judged, should how to design the shape function that matches.Though this processing mode provides the still result of suboptimum of energy usefulness usually.Thereby better, the overall analysis of the output state of being tried to achieve is a singular value decomposition." singular value decomposition " this term has fixing meaning to one skilled in the art.
Though can carry out singular value decomposition, preferably, corresponding with the part of the characteristic vector of the matrix of described quadratic form according to the matrix of totally trying to achieve quadratic form and the described shape function that matches of the output state of being tried to achieve.For trying to achieve the matrix of described quadratic form, such as the weight factor of every kind of output state can be write and write abreast each other each column vector as column vector.Obtain coefficient matrix thus.Described coefficient matrix and its transposed matrix are multiplied each other.Matrix product produces the matrix of the symmetry of a quadratic form, then can be in the hope of the characteristic vector of this matrix.
Can only try to achieve described characteristic vector and then " intelligently " select should with the corresponding characteristic vector of the shape function that matches.But in a kind of preferred design, try to achieve the characteristic value of matrix of the symmetry of described quadratic form.In this case, the described shape function that matches is corresponding with the characteristic vector of distributing to maximum characteristic value.
Such as can be according to size to described characteristic value sort (at first being maximum, is minimum at last).In this case, such as n characteristic value before can selecting, such as 5,10 or 15 characteristic values.Also can select preceding x percentage of described characteristic value.Also can select all characteristic values bigger than threshold value.Scheme as an alternative, this threshold value may be prescribed as absolute value or are defined as the mark of maximum characteristic value.

Described computer program 5 has machine code 8.This machine code 8 can directly be carried out by computer 4.This machine code is in operation by computer 4 and carries out.Come the operation of the described computer 4 of brief explanation below in conjunction with Fig. 2.
According to Fig. 2, computer 4 is at first realized rolling model 9 (replenishing referring to Fig. 3) in step S1.In step S2, the desired output state Z of the state Z of the rolled piece 1 that computer 4 receptions are banded and banded rolled piece 1
*State Z relates to the state of banded rolled piece 1 before rolling, and desired output state Z
*Then relate to the banded state of rolled piece 1 after the operation of rolling.At least described state Z is within the predetermined state range.Preferred desired output state Z
*Also be within the desired state range.
In step S3, computer 4 determines that temporary transient frame is provided with G.Described frame is provided with predetermined the setting within the scope that G is in the rolling machine frame 2,3 that is modeled.This frame is provided with G such as stipulating, relates to flat pass and also relates to upset pass and how the rolling machine frame 2,3 that causes passage is set.
In step S4, computer 4 is provided with G according to rolling model 9, state Z and frame and tries to achieve output parameter A.Rolling model 9 thereby according to providing described output parameter A for its state Z given in advance with for its frame given in advance is provided with G.Described output parameter A has the weight factor a of some usually, and described weight factor a shows, distributes to the shape function that matches of corresponding weights factor a
(this operation of rolling is provided with the G definition by the corresponding state Z and the corresponding frame of the rolled piece 1 of band shape) to what extent occurs in the rolled piece 1 of described band shape after the operation of rolling.Described weight factor a tries to achieve such as carrying out by means of the well-known gal of those skilled in the art the Liao Dynasty gold (Galerkin) method.Scheme as an alternative, described weight factor a is such as trying to achieve by means of a kind of flexible program (Variationsansatz).For the purpose of orderliness is clear, to mention at this, (and also in other place) uses subscript i extraly in Fig. 3, is used for expression, relates to the multiple shape function that matches that correspondingly differs from one another at this
Weight factor a or the like.Described output parameter A quantitative description at least a the material flow that occurs in the rolled piece 1 in band shape is being set by state Z and frame in the defined operation of rolling of G.In case of necessity, described output parameter A can describe other characteristic.But the characteristic of being mentioned at least obtains quantitative description.
In step S5, computer 4 is checked, output parameter A that whether is tried to achieve (within the tolerance that allows) and desired output state Z
*Corresponding.If not this situation, computer 4 just jumps to step S6 so, makes described frame that G is set at computer described in the step S6 and is being provided with within the scope and changes.Computer 4 turns back to step S4 from step S6.
If output parameter A that is tried to achieve and desired output state Z
*Fully consistent, computer 4 just jumps to step S7 so.In step S7, computer 4 is provided with G according to the last frame of determining and triggers corresponding rolling machine frame 2,3.
Repeat implementation step S2 to S7, up to the method that should finish Fig. 2 according to step S8.
In the above in conjunction with in the illustrated processing mode of Fig. 2, computer 4 online computer program 5 together with control milling train row.This processing mode is preferred.Scheme as an alternative, computer 4 can not be control device and the computer 4 off-line ground computer program 5 that are configured to the milling train row.In this case, can be replaced the user who in this unshowned step, preserves the corresponding output parameter A that tries to achieve or output it to computer 4 by unshowned step such as step S7.
According to Fig. 3, so constitute rolling model 9, make it be based upon on the equational basis of mathematics-physics.The equation of described mathematics-physics can comprise algebraic equation according to Fig. 3.Scheme or additional project as an alternative, the equation of described mathematics-physics can comprise (part) differential equation according to Fig. 3.In addition, according to Fig. 3, in the scope of rolling model 9, use the shape function that matches
That is to say and be corresponding rolling machine frame 2,3 shape function that customizes of the typical passage of rolling machine frame 2,3 in other words
Rolled piece 1 is for banded in the example of being explained, can only comprise flat pass so that be used for the scope that is provided with that frame is provided with G in this example.Scheme can make the described scope that is provided with not only comprise flat pass but also comprise upset pass in the example of being explained as an alternative.In both cases, described material flow comprises that at least the rolling direction x transverse to the rolled piece 1 of band shape that is to say along the cross-current of the width of banded rolled piece 1.Preferred described material flow also comprises along the longitudinal stream of rolling direction x.
For the order of pure flat pass, can try to achieve the profile and/or the glacing flatness of banded rolled piece 1 by means of rolling model 9.For some passages, flat pass and upset pass hocket, and not only the so-called dog bone of the rolled piece 1 of quantitative description band shape forms phenomenon (referring to Fig. 4) to the output parameter A of described rolling model 9 but also its bulge of quantitative description forms phenomenon (referring to Fig. 5) and necking down forms phenomenon (referring to Fig. 6) for the result of these passages.So-called dog bone (dog bone) may occur in upset pass, and bulge and necking down then may occur in flat pass.
The methods of the generation of described rolling model 9 are arbitrarily in principle.Conclusive is that rolling model 9 is based on the shape function that matches
For this reason, although use the equation of mathematics-physics, this rolling model 9 also has online ability.
Explain in detail below in conjunction with Fig. 7 and 8 pairs of a kind of feasible generation methods that are used for rolling model 9.
But also to point out the generation method that this generation method is a construed as limiting once more.It only must have on the result with regard to Fig. 7 and 8 characteristics of being explained with regard to rolling model 9 limits this rolling model 9.On the contrary, it is unimportant whether to generate described rolling model 9 this point by processing mode illustrated in Fig. 7 and 8.
According to Fig. 7, formation base model 9 ' in step S11 at first.This basic model 9 ' is according to the equation of Fig. 8 based on the mathematics-physics identical with rolling model 9.And the difference between the rolling model 9 is, uses general shape function for generating basic model 9 '
That is to say the shape function that is not that specially the description for the specific operation of rolling customizes
Such as described general shape function
Be based upon on the basis of finite element analysis method.For generating basic model 9 ', need the general shape function of greater number
(thousands of in typical case, in some cases above 10000).
Described basic model 9 ' is not to generate in the scope by generation method of the present invention.Scheme as an alternative, this basic model 9 ' also can obtain in other mode.Sometimes even can be at the suitable basic model 9 ' of commercial acquisition.
In step S12, be the base state Z ' of the rolled piece 1 of described basic model 9 ' band shape given in advance.In addition, in the scope of step S12, G ' is set for basic model 9 ' basic frame given in advance.Described base state Z ' is within the predetermined state range.Described basic frame is provided with G ' and then is in predetermined the setting within the scope.
In step S13, correspondingly try to achieve output state A ' by means of described basic model 9 '.This output state A ' describes by the weight factor a ' of some according to Fig. 8.Described weight factor a ' correspondingly represents, distributes to the general shape function of corresponding weights factor a '
(the described operation of rolling is provided with G ' by base state Z ' and frame and defines) to what extent occurs in the rolled piece 1 of band shape after the operation of rolling.The output state A ' that is tried to achieve is preserved in step S13.Described weight factor a ' can be to try to achieve with the similar mode of weight factor a.Difference is, weight factor a ' and general shape function
Relevant, weight factor a then with the shape function that matches
Relevant.
In step S14, check whether should finish asking for of output state A '.If not this situation, that just turns back to step S12.Otherwise continue described generation method with step S15.
Totally analyzing in step S15 to the output state A ' that tried to achieve.In step S16, try to achieve the shape function that matches then according to the analysis of step S15
The shape function that matches
Number significantly less than general shape function
Number.The shape function that matches
Number usually far below 100, such as being lower than 70, in some cases even be lower than 50.
In step S17, generate rolling model 9.Using the shape function that matches of in step S16, trying to achieve
Situation under generate rolling model 9.
In step S18, generate machine code 8 according to rolling model 9, this machine code 8 can directly be carried out by computer 4 and the execution of this machine code 8 causes the top illustrated method of operation of computer 4.Machine code 8 is corresponding with computer program 5 generally at it, then with this machine code 8 such as being kept on the data medium 7.
Be to implement step S15 and the S16 of Fig. 7, according to Fig. 9 such as the overall singular value decomposition of the output state A ' that can at first in step S21, implement to be tried to achieve and then in step S22, be chosen in the singular value that occurs to the full extent.For the purpose of orderliness is clear, to mention at this, not only select a unique singular value certainly, but select a plurality of singular values.But the number of selected singular value is significantly less than general shape function
Number (typically the former is 100 to the maximum, and in contrast to this, the latter then is thousands of).Then in step S23, for each singular value is tried to achieve the affiliated shape function that matches
Scheme as an alternative, can be according to output state A ' totally carry out principal component analysis (Hauptkomponentenanalyse).The face that is preferably as follows in this case is in conjunction with equally handling that Figure 10 explains in detail.
According to Figure 10, generator matrix M in step S31 at first.Form row of described matrix M such as the weight factor a ' of every kind of output state A ' that is tried to achieve.Described output state A ' equally can be placed as the row of matrix M at this.But, the matrix of preferably so trying to achieve-below be called state matrix-also be not matrix M.Because preferably will try to achieve the mean value of corresponding row for each row of described state matrix.From the matrix element of corresponding row, deduct described mean value then.The matrix of changing by row of so trying to achieve is formed on the matrix M that generates among the step S31.
In step S32 with matrix M and its transposed matrix M
TMultiply each other.The matrix product of trying to achieve in this way produces the matrix Q of the symmetry of quadratic form.
In step S33, try to achieve the characteristic value of matrix Q of the symmetry of described quadratic form.In step S34, select the highest characteristic value.Can come a limiting value given in advance in a different manner, select described characteristic value until this limiting value.Such as characteristic value that can an absolute number given in advance.Scheme as an alternative, percentage that can characteristic value given in advance.Equally can an absolute value given in advance and select all greater than or greater than/equal the characteristic value of this numerical value.Also can be with all characteristic values divided by the characteristic value of maximum and select all specific characteristic values, for these characteristic values and the quotient between the characteristic value of maximum greater than or greater than/equal a predetermined limiting value.
In step S35, try to achieve and the corresponding characteristic vector of selected characteristic value in step S34.In step S36, try to achieve the corresponding shape function that matches according to the characteristic vector of the matrix Q of described quadratic form
If deduct mean value according to preferred processing mode in the scope of step S31 from matrix element, that just is added to mean value in the scope of step S36 on each component of characteristic vector.
The top processing mode of explaining is familiar with by those skilled in the art as such processing mode.Thereby there is no need about the further explanation of this respect.
The same as already mentioned, the shape function that described rolling model 9 usefulness match
Come work.Can come state Z given in advance with a kind of corresponding form that is complementary in the scope of the schematic diagram of Fig. 3 in other words in the step of Fig. 2 at this.Scheme can make described rolling model 9 have preposition module 10 and primary module 11 according to Figure 11 as an alternative.In this case, in preposition module 10, state Z is converted to the described shape function that matches
Component k.In primary module 11, according to the described shape function that matches
Component k and described frame G be set try to achieve output parameter A.Certainly correspondingly in the scope of the processing mode of Fig. 7 to 10, generate described rolling model 9 in this case.
The present invention has many advantages.Especially almost the quality with (typically based on finite element analysis method) basic model 9 ' is the same high for the quality of rolling model 9.On the contrary, be used to try to achieve the then greatly reduction of computing cost of output parameter A, because compare the shape function that only uses several minorities with basic model 9 '
According to this situation, described rolling model 9 especially can onlinely use.
Top explanation only is used to explain the present invention.On the contrary, protection scope of the present invention only should be determined by the claim of enclosing.Especially in an embodiment the measure of being explained also can be used on the rolled piece 1 of non-band shape.
